Examining the following ant build file. Could someone please tell me
why it is continually running the "create" task even though I'm trying
to set the property after it is run once? Basically I don't care if I
do it this way or another way...I just want to know how to keep tasks
from being run more than once. It seems to be working in the init task
but not in the other tasks where I mimic the same property behavior.
Thanks for your help.
